CANDY-COOLING APEARATUS.

Specification of Letters Patent.

Patented Mar. 23, 1915.

Application filed April 14, 1913. Serial No. 761,128.

T all whom it may concern:

Be it known that I, DAVID H MPHREY, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of ()hio, have invented certain new and useful Improvements in Candy-Cooling Apparatus, of which the following is a specification.

This invention relates to candy cooling apparatus, and the invention consists in the construction and combination of parts substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective View of the apparatus, and Fig. 2 is a cross section looking to the right on line 22, Fig. 8, and enlarged as compared with Fig. 1. Fig. 3 is a side elevation of the device sectioned at the discharge end of its pendulum or counterweight. Fig. at v is a cross section of the pendulum on line wa:, Fig. 3. Fig. 5 is a plan view of the apparatus partially sectioned at one end, and Fig. 6 is an enlarged'vertical sectional elevation on a line centrally through the machine and broken out in the middle, said line being substantially on 66, Fig. 5, and disclosing the water course through the apparatus and features of construction incident thereto. Figs. 7 and 8 are detail views of the gaskets for the head ends of the apparatus.

Inmaking candy difl'erent forms of manipulation are necessary to make it attractive and appetizing, and the manner in which the candy is cooled also plays an important part. Heretofore, the general practice has been to employ marble slabs or smoothed-off fiat stones, but marble is porous, as also is stone, and the grease used to prevent the candy from sticking is absorbed by the marble and becomes rancid, putrid and disease breeding. Glass or steel are better so far as sanitation is concerned but among other objections these materials become warm too rapidly and are inefficient.

My present improved apparatus overcomes these defects and many others which menace the perfect product. To illustrate, one of the troubles in making candy is in its freezing or getting too cold in a brief time. This applies more particularly to what is known as pull candy. My experience and observation warrant me 1n saying that, with the greatest care, not more than one batch in three can be gotten in perfect Again, with my apparatus the operator can commence immediately to turn the edges of the candy, as the edges are very thin; while by any other means for cooling he must wait fifteen to thirty minutes for the candy to get cool enough to manipulate. This makes window display by my apparatus attractive because it depends on action and my machine requires action all the time. Again, bymy machine the'candy is deepest and warmest at the middle and hencethe operator can be away, if necessary, for fifteen to thirty minutes most any time and start in again nearly wherehe left off without the candy becoming toocold for proper working. Furthermore, this improved cooler hasabout three times the capacityof any other knownto me andlargely because the plates of the pan are built of pure copper, which is the'best conductor, and has a quality which prevents candy from sticking to it. This is not true of other metals and materials, and candy makers frequently burn their fingers because the candy on other coolers is as thick and hot at the edges as any other place. On my cooler the edges are always cool. The concave form of cooler especially prevents bucklingor bulging of the metal, and since the water'is under pressure it goes to all parts equally. I have in fact been experimenting for a long time to find a way to run a thin sheet of water under pressure under a thin sheet of metal without bulging the metal and making the attempt abortive, until at last I hit upon the novel and successful plan herein set forth. Another drawbackis overcome by employing two sheets of curved metal plates under tension and so disposed that they are uni-' formly separated with a narrow space between and that the water cannot squash out from beneath where the pressure is being.

applied. By discharging the waste water between a transparent Wall, the cooler is made very attractive for display purposes and the equalizing balance of the pendulous and weighted discharge portion of the cooler is especially advantageous in giving stability to the device in working the candy while in the pan or trough. A rocking movement of the pan or trough promotes rapid cooling of the candy by spreading it in sheet form back and forth until of uniform thickness.

The apparatus as herein shown has a support consisting of a tripod or three legs a at one end and two legs a at the other end, and the tripod has an extension or stem 2 which serves as the immediate support for the cooling pan or cooler 0 at that end. A horizontal bearing 5 is rigid on or with said extension 2 and supports the tubular spindle 5 of the approximately T-shaped head it at that end of the pan 0. Said spindle has a nipple 6 of substantially elbow shape in this instance fixed on its outer end on which the rubber hose 7 for the inflowing water is shown as engaged. Of course any other suitable water supply connection than hose may be adopted, especially if the apparatus be built into stationary water connections. In that event, also, its leg supports might be variously changed and substituted according to conditions of location and position where the cooler is installed. The cooler or pan 0 is transversely curved as seen in Fig. 2, and is constructed with two thin sheets of a suitable metal, say of copper, with a highly finished working surface, spaced apart relatively as shown in Fig. 2, and so as to maintain a mere film or sheet of water between them. It is of course planned to have the said water space uniform in all its portions and hence the said sheets are duplicates and spaced apart at their side edges by a suitable gasket or the like and confined in longitudinal slots in the sides or border tubes 8, but otherwise or between its sides the said space is open for the flow of the cooling water through the same from end to end. Supply of water is by the hose 7 and connections into the head it, and the discharge from the pan is through the opposite head A and thence into a balancing member m. The waste is from the bottom of said member by a tubular projection 9 at its center and bottom as hereinafter described, and said member is rigid with the cooling pan, and it acts as a sort of pendulum or counter-balance for said pan within limits as wll presently be seen. The position or location of member m is next within the legs a and is constructed with two transparent sheets 9 of glass set into a suitably heavy and. rigid frame of which the cross head 71, of the cooling pan constitutes the upper portion. That is, the cooling pan frame comprises the two heads 72. and it and the side tubes 8 in which the edges of the pan proper are secured and sealed water tight, and the frame of balancing member m comprises the head A at its top, the side tubes 11 detachably screwed to head it and the bottom head k with which the side tubes have a rig d connection. The glass sides 9 are flat and spaced apart relatively as seen in Fig. 6, and about the same as the plates of the cooler or thereabout, and water from the'cooler or pan 0 is discharged against the inner sides of the glass sheets from the head it through the distributing member or part at. The said part has a nozzle-like appearance in cross section but in fact is equal in length to the width of said glass plates and is provided with a series of holes or openings 0 at an outward and downward inclination on opposite sides through which tie water is jetted upon said glass plates, whence it flows visibly down the sides thereof to the discharge through head if into the stationary trough-shaped part 20 beneath. The said trough, so-called, is curved to the segment of a circle between its ends corresponding to the swing of member m, and has a slot lengthwise in its top entered part way by the discharge projection 9 on the bottom of the head if and which traverses said slot as the member swings from side to side in or during the manipulation of the candy. Buffers 24 in the ends of said trough serve as cushioning stops for the said discharge projection 9, and said trough itself discharges into waste pipe 25. In this instance said trough has an internally threaded neck 26 with a flange about its bottom to fix it upon the floor and in which the said pipe has screw connection.

The cooling liquid or water is suitably distributed under pressure to the cooling pan by means of a perforated rubber or like gasket or diaphragm d midway in head it and the main discharge of the water is preferably at the ends of this diaphragm where a group of perforations 22 are provided. If desired, the perforations which are shown at intermediate points in the gasket may be omitted to cause all the water to flow to the sides of the pan before passing through the space between the plates to head 72 It is also desirable to have this space practically packed with water notwithstanding that it is kept on the move and to this end a somewhat similar diaphragm cl is placed in the head it. The form of these diaphragms are shown in Figs. 7 and 8 respectively and diaphragm d is perforated similarly to diaphragm d to restrict and distribute the water so that pan 0 will be uniformly cooled. By having a series of comparatively small openings for the passage of the water at both ends of the pan the uniform distribution as well as the sustained pressure of the water in the pan is materially promoted. In this connection, also, and as a very material advantage in the use of my apparatus, 1 utilize the rocking movement of the pan as a further means of temperature equalizer of the water to offset the irregularities of heat imparted by the hot candy poured into the pan. Such rocking motion induces a transverse flow of the water which is across the end to end flow and compels uniformity of temperature of the cooling medium. A back pressure of the water to keep the cooling space of the pan 0 full at all times may be obtained solely by limiting the number or size of the discharge openings 27 in head 72., and which openings control the flow of water to the nozzle portion n. The two curved copper plates are held apart at the sides by separating strips 28 and at their ends by spring blocks 29, see Fig. 5. No separators are used between said plates as the curvature thereof gives the necessary rigidity and strength to prevent deflection or bending of the plates between their ends under the load or any down pressure therefrom and the side tubes 8 to which the plates are soldered also serve as stiffeners. Intake nipple 6 is removable, and a gauze or wire mesh strainer 29 is placed within pipe 5 at this point to prevent foreign matter from passing into the cooler and clogging it up, especially at the small openings and perfo rations therein.

The cooler is relatively small for the work accomplished by it and this is of advantage as valuable space in the candy shop may be saved and utilized for other purposes.
